Deny any connection with row about farm animal (6)
I believe the answer is:
disown
'deny any connection with' is the definition.
(I've seen this before)
'row about farm animal' is the wordplay.
'row' becomes 'din' (both can mean a loud disturbance).
'about' indicates putting letters inside.
'farm animal' becomes 'sow' (I've seen this before).
'din' going around 'sow' is 'DISOWN'.
(Other definitions for disown that I've seen before include "Refuse to have anything to do with" , "Repudiate - disinherit" , "Repudiate, disclaim" , "Abnegate" , "Refuse to be associated with (something/someone)" .)
